DAMM: Australia Approves VHF TETRA Frequencies
Tuesday, October 22, 2019 | Comments

DAMM Australia obtained approved VHF TETRA frequencies in Australia and can now offer users an additional band of spectrum.

Advantages of VHF frequencies include improved RF propagation in rural, wooded or undulating hilly areas; more economic coverage when deployed underground using distributed antenna systems (DAS); and expanded telemetry coverage, the company said.

“VHF frequencies are extremely well suited for Australia with its vast rural areas as well as its many mining operations,” said Geoff Wood, technical director at DAMM Australia. “We are delighted that we can now offer VHF in TETRA mode to our customers.”

To support the VHF frequencies, DAMM offers the VHF FT5 TETRA radio developed by DAMM and Funktel. The radio can be operated using the DAMM MultiTech Outdoor System (BS422) in VHF.

It is possible to run both VHF and UHF on the same network using separate BS422 base stations operating the DAMM TetraFlex software. This makes it possible to extend an existing UHF network to include VHF in areas where this frequency band is more advantageous, the company said.
